Definitions

  • the invention relates to a device for spraying paint or plastic powder, with a spray gun through which compressed air flows and a container for the material to be sprayed.
  • Powder spray guns have also become known in which only a small amount of halon is sprayed into the powder or paint cloud in the event of a fire. However, it is disadvantageous that there is no reliable extinguishing effect.
  • the method for operating such a device should be simple and reliable and only require a small outlay, with the risk of personal injury being excluded.
  • the drawing shows a powder or paint spray gun 2 with a feed line 4 for the material to be sprayed.
  • a shut-off valve 6 for the material to be sprayed is installed, which can suddenly shut off the material flow.
  • a pressure vessel 5 for a non-combustible gas is connected to the feed line 4 via a valve 8, which can also be switched quickly, the valve 8 either via a fire sensor 1 or a high (over) voltage sensor 7 can be switched.
  • the size of the pressure vessel 5 is to be chosen so that the gas contained in it can completely fill the space 3 in the relaxed state, in which a fire has started or can occur.
  • the gun 2 is grounded in a known manner and can have a conventional structure with a driving nozzle and a supply of compressed air, which are not drawn to simplify the illustration.
  • the method according to the invention works as follows:
  • the non-combustible gas preferably CO2
  • the non-combustible gas now flows into the feed line 4 or into the gun 2 and from there to the room 3.
  • the oxygen in this area is then displaced and a fire is thereby suffocated or excluded.
  • the supply of the material to be sprayed is terminated via a valve 6, so that a fire or the occurrence of a fire is reliably prevented even after the incombustible gas has escaped from the room 3.
  • the installer can device can be put back into operation.
  • CO2 is commercially available as a non-combustible gas in suitable small containers and a connection of the same in the device according to the invention is possible without major technical effort, an ideal solution to the problems at hand can be said in view of the safe fire extinguishing or prevention.
  • the size of the pressure vessel 5 or the amount of the incombustible gas to be used can be determined empirically by experiment.
